Struct Token 

pub struct Token(/* private fields */);

A transaction generation token used to identify the owning transaction of a ChainLock and arbitrate priority when contention occurs.

Implementations

impl Token

pub const UNLOCKED: Self

Token value representing an unlocked ChainLock.

pub const MAX: Self

Maximum possible token value, representing the lowest possible transaction priority.

pub const fn new() -> Self

Creates a new unlocked token.

pub const fn is_valid(&self) -> bool

Returns true if this token is valid (i.e., not the unlocked token value).

pub const fn is_reserved(&self) -> bool

Returns true if this token is a reserved token (e.g., per-CPU token used during context switch state save/restore).

pub const fn value(&self) -> u64

Returns the raw 64-bit integer value of this token.

Trait Implementations

impl Clone for Token

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Token

impl Debug for Token

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Token

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Token

impl Ord for Token

fn cmp(&self, other: &Self) -> Ordering

This method returns an [Ordering] between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Token

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for Token

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
